**A satellite orbits Earth in a pattern where its altitude increases by 15% each orbit due to atmospheric adjustments. If initial altitude is 420 km, what is it after 4 orbits?** Curiosity about space mechanics is growing, especially as satellite technology shapes daily life from GPS navigation to global internet coverage. Among intriguing orbital behaviors, a model where a satellite’s altitude rises 15% per orbit due to atmospheric drag and adjustments sparks attention—both for its science and its real-world impact. Could this gradual climb really define how satellites evolve beyond their launch altitude? Let’s explore how altitude changes unfold after four orbits from a starting point of 420 km. When a satellite orbits Earth and experiences atmospheric drag, its effective altitude can gradually increase as energy shifts within the orbital system—driven by complex interactions in low Earth orbit. While satellites lose altitude in traditional orbital decay, specialized adjustments such as controlled reboost or atmospheric buoyancy shifts can create a net rise pattern akin to a 15% growth递进 per orbit in altitude. Using this scenario, starting at 420 km, the altitude after each orbit follows a multiplicative pattern: each increase compounds on the previous, not climbs from zero. **Understanding the mathematical progression:**
After orbit 1: 420 × 1.15 = 483 km
After orbit 2: 483 × 1.15 ≈ 555.45 km
After orbit 3: 555.45 × 1.15 ≈ 638.77 km
After orbit 4: 638.77 × 1.15 ≈ 734.14 km
